if u gonna do this next year just buy a small bag of potting soil. i have a 20 pound bag if they got a smaller size go for it. maybe a 10 to 5 lb. bag will be fine for 3 plant or more. good luck.
2 gallon pots are considered pretty small, good for 2-3 foot plant
1 cubic foot of soil will fill about 5 gallons of volume, soil bags are often labeled in cubic feet
